I ibf 'nrronMErs edges of said locking members will meet at the medial line thereby bracing one another and bracing the adjacent walls of the filler, and consequently resisting collapsing strains exerted on the fi1ler.- r

In Figures 6 and 7 a flat 10 is employed of an area to cover a filler and be interposed between adjacent fillers in the case. Said filler is shown as formed at the corners with locking elements or tongues 11 of triangular form, the bases of the tongues being parallel with adjacent side edges of the flat; Initially the tongues project beyond the adjacent side edges. ,The flat is scored as at 12 at the bases of the locking elements 11 for the bending down thereof, the scores 12 being parallel with and inward from the planes of the adjacent side edges. The flat is slitted at the sides of a pair of tongues as at 13", the slots extending inwardly to the scored lines 12, said slots being thus on parallel oblique lines so that the tongues are partly within the side edges of the flat and partly projecting beyond said side edges when the tongues are in the plane of the flat and before being bent at substantially right angles thereto to enter the cells. The tongues l1 are adapted to be entered in the corner cells against the adjacent outer walls thereof to bracethe same and lock the filler against collapsing after the manner of the tongues 11. The arrangement referred to results in marginal edge portions 10 between the respective corner locking members and adapted to overlie the filler over the whole area and at the sides thereof, so that the edge portions will not bepressed into the fillers by the weight of eggs above the flat.

In the form of flat shown in Figures 8 and 9, the locking elements are produced inwardly from the edges, the openings produced by the bending down of the elements being surrounded'on all sides by the material of the flat. The locking elements 11 of Figures Sand 9 are so disposed as tolie at the inner adjacent sides of the corner cells instead of within said corner cells as in the previously described constructions, in orderto brace the-sides of the cells adjacent to which said locking elements are disposed. To produce. the triangular looking elements 11, I produce slits 13 at an obtuse angle to each other and a slit 13 transverse to the first-mentioned slits at the point of convergence of the latter. Also, the material is scored as at 12 at the bases of the elements 11. i A

In Figure 10 a locking element10 of strip form correspondinggenerally with the looking element of Figures 1 to 5 is shown but in which the locking elementsll are of the form shown in Figures 8 and 9 and produced inwardly from the ends'ofthe strip. The slits 13, 13 correspond with the slits 13", 13 and the score lines 12 at the bases of the elements 11 correspond with the score lines of the other figures, particularly F igures S and 9. The end edges of'the strip 1O converge'at the medial line to conform to the corner cells when the strip 10 is placed obliquely.

In the form shown in Figure 11 the looking strip 10 is formed with locking mern bers 10 at the end produced by slitting the strip longitudinally as at 13 from each end along the medial line or approximately so and bending down the material at'the sides of theslot on the oblique score lines 12, said score lines extending from the corners and convergent at the medial line of the strip at the inner end of the slits 13.

I would state in conclusion that while the illustrated examples constitute practical embodiments of the invention, I do not limit myself strictly to the mechanical details herein illustrated, since manifestly the same can be considerably varied without departure from the spirit of the invention as defined in the appended claims.

Having thus described my invention, 1 claim:

1. As a new article of manufacture, a device for use with a collapsible egg-case filler, consisting of an element adapted to lie at the top or bottom of the filler and having members adapted to be disposed in cells of the filler against and parallel with walls thereof to constitute a brace for resisting collapsing of the filler.

2. As a new article of manufacture, a device for use with a collapsible egg-case filler consisting of an element adapted to lie flat on a face of the filler over cells thereof and having locking tongues adapted to be disposed in positions to enter in cells of the fillers and lie against and parallel with walls thereof to constitute a brace for resisting collapsing of the filler.

3. Asa new article of manufacture, a flat for eg -case fillers having locking members adapted to enter cells of the filler to lock the same against collapsing, said locking members being disposed so as to lie along and parallel with't'wo' adjacent cell walls.

1. As a new article of manufacture, a locking element for collapsible eg -case fillers adapted to be disposed obliquely between diagonally opposite corners of the filler and having triangular locking members on the ends thereofat a face of said element and adapted to be disposed in planes substantially at right angles to adapt them to enter diagonally opposite corner cellsflof'the filler to lie against the adjacent outer walls of the said corner cells, the body of said element having end edges convergent at approximately the medial lineof said element to conform to the planes of said locking members when in use, said locking members having a at theif base's V opposite Walls d ffthe'bll t6lhav a, "bracing relation strains,
